The CentOS Project is pleased to announce the immediate availability of CentOS 7 for x86_64, including images for docker, and various cloud providers. There are many fundamental changes in this release, compared to previous releases of CentOS. Notably the inclusion of systemd, Gnome3, and a default filesystem of XFS. For more information about what makes CentOS 7 stand out, please see our release notes.

Ubuntu, Fedora etc are better than CentOS?
Really?
Ubuntu seems to change according to the whims of Canonical. Mint wouldn't be where it is today if it wasn't.
Fedora, and I am a fan of the distro is not for the timid or newbie. It is unashamedly a bleeding edge distro. As such it is sometimes very fragile.

CentOS is my distro of choice these days. Stable and does the job I want it to. Yes, I use it on the desktop as well as servers and in VM's. Sure the new Anaconda can throw a few people but honestly, how much of the life of a linux system is 'Installation'?
(Unless you are a Journalist that is...)

Also, you get the updates that RH make to RHEL 5,6 and now 7. 10 years of updates should be enough for anyone in most circumstances.
